BACKGROUND AND SUMMARY OF THE INVENTION

Patients are oftentimes transported from location to location in a hospital or other healthcare facility on a stretcher that is highly mobile. Patients also spend a great deal of time during their stays in a hospital on a hospital bed located in a patient room. Hospital beds typically have various systems, such as drive and articulation mechanisms for raising, lowering and tilting a patient support deck, siderails with television, radio and other controls, patient weigh scales, and so on. Thus, hospital beds are usually less mobile than stretchers due to the increased weight of the hospital beds. It is sometimes difficult and time consuming to transfer patients between stretchers and hospital beds. On occasion, caregivers sustain back injuries while transferring patients. Thus, it is desirable in healthcare facilities to minimize the number of patient transfers between hospital beds and stretchers.

According to the present disclosure, a transfer top adapted to carry a patient is transferable between a mobile base and a stationary support structure (also referred to as a docking station or a patient care module). Thus, instead of transferring a patient between a hospital bed and a stretcher, the entire transfer top with the patient thereon is transferred between the mobile base and the stationary support structure.

An illustrative docking station includes a support rail extending away from a hospital room wall, and adapted to support a transfer top. In some embodiments, the docking station includes a pair of spaced-apart support rails and a pair of siderails. Each siderail is coupled to a respective support rail.

According to the present disclosure, a patient care module comprises a pedestal and at least one support arm coupled to the pedestal and adapted to support a transfer top. The transfer top is transferable between the pedestal and a mobile platform. In some embodiments, the patient care module includes at least one service outlet coupled to the pedestal. In other embodiments, the patient care module includes an overbed table coupled to the pedestal and movable between a storage position extending in a perpendicular relation with the support arm and a use position extending in a parallel relation with the arm.

DETAILED DESCRIPTION OF THE DRAWINGS

Throughout this description, (1) the terms “docking station,” “pedestal” and “patient care module” are used interchangeably, (2) the terms “transfer base,” “wheeled base,” “mobile base,” “stretcher base,” “transport trolley” and “mobile platform” are used interchangeably, and (3) the terms “transfer top,” “mattress support deck” and “patient support deck” are used interchangeably.

According to the present disclosure, a docking station 100 includes a pair of support rails 102 extending horizontally away from a wall 104 of a hospital room 106 in a cantilevered fashion as shown best in FIG. 1. The support rails 102 are spaced apart to define a docking space 108 between the support rails 102. A pair of support legs 110 are coupled to the outer or distal ends of the support rails 102 and extend downwardly therefrom to engage a floor 112 of the hospital room 106. Each leg 110 includes an upper portion 114 and a lower portion 116 that telescopes into and out of the upper portion 114. The docking station 100 also includes a pair of siderails 118. Each siderail 118 extends upwardly from a respective support rail 102 as shown, for example, in FIGS. 1-4.

A stretcher 120 includes a transfer base 122 and a transfer top 124 supported by transfer base 122 as shown in FIG. 1. The transfer base 122 and transfer top 124 are also referred to herein as the stretcher base and stretcher top. The transfer top 124 is detachable from the transfer base 122, and is attachable to a carrier or carriage 126 of the docking station 100. The carrier 126 is translatably mounted on the support rails 102 to move along the support rails 102 as will be described in further detail below. In the illustrative embodiments, the carrier 126 includes rollers or wheels which ride in tracks provided in the support rails 102. In alternative embodiments, the transfer top 124 is directly mounted on the support rails 102 to move along the support rails 102.

During transfer of the transfer top 124 from the transfer base 122 to the docking station 100, the stretcher 120 is moved in the direction of arrow 128, shown in FIG. 1, so that the transfer top 124 is received in the docking space 108. A first set of coupling mechanisms are operated to release the transfer top 124 from the transfer base 122 and a second set of coupling mechanisms are operated to couple the transfer top 124 to the carrier 126 supported by the support rails 102. Thereafter, the transfer base 122 is moved away from the docking station 100 in the direction of arrow 130, shown in FIG. 2, leaving the transfer top 124 in the docking space 108 supported by the support rails 102 as shown in FIGS. 2-4. The first and second sets of coupling mechanisms may include, for example, grippers that grip portions of the transfer top 124 or portions of the docking station 100, clutches that engage portions of the transfer top 124 or portions of the docking station 100, manually actuated pins that are received in apertures formed in the transfer top 124 or the docking station 100, solenoid actuated plungers that are received in apertures formed in the transfer top 124 or the docking station 100, hooks or latches that catch on posts or the like, blades that extend into and retract out of associated slots, or any other type of conventional mechanisms suitable to releasably couple the transfer top 124 to the carrier 126 and to the transfer base 122.

The transfer top 124 includes an articulated deck 132 and a mattress 134 supported by the deck 132. The deck 132 includes three sections and the mattress 134 includes associated portions that are supported by the three sections of the deck 132. Thus, the deck 132 cooperates with the mattress 134 to provide the transfer top 124 with a head section 136, a seat section 138, and a foot section 140 as shown in FIG. 3. The docking station 100 includes drive mechanisms 142 that automatically couple with articulation mechanisms 144 included in the transfer top 124 when the transfer top 124 is coupled to the support rails 102 as shown in FIG. 2. Likewise, the stretcher 120 also includes drive mechanisms 146 that interact with the articulation mechanisms 144 of the transfer top 124 when the transfer top 124 is coupled to the stretcher 120.

Siderails 118 include controls 148 for inputting patient and/or caregiver commands that control the drive mechanisms 142 of the docking station 100. Commands from the controls 148 on the siderails 118 actuate the drive mechanisms 142 included in the docking station 100 which act through the articulation mechanisms 144 included in the transfer top 124 to move the sections 136, 138, 140 relative to the support rails 102 when the transfer top 124 is coupled to the docking station 100. The seat section 138 of transfer top 124 is coupled to the carrier 126 supported on the support rails 102. In addition, the siderails 118 are coupled to the carrier 126. Thus, the siderails 118 and the transfer top 124 move with the carrier 126 as the carrier 126 moves along the support rails 102. As shown in FIG. 1, the stretcher 120 also includes controls 150 mounted on stretcher siderails 151 that are used to control the drive mechanisms 146 of the stretcher 120. Thus, the transfer top 124 is articulatable to a variety of positions when coupled to the docking station 100 and when coupled to the stretcher 120.

Illustrative transfer top 124 is moveable between a horizontal position, shown in FIG. 2, having the upper surfaces of the mattress portions corresponding to the head, seat, and foot sections 136, 138, 140 in substantially coplanar horizontal relationship with one another and a chair position, shown in FIG. 3, having the head section 136 pivoted upwardly relative to the seat section 138 to a raised position and having the foot section 140 pivoted downwardly relative to the seat section 138 to a lowered position. During movement of the transfer top 124 into the chair position shown in FIG. 3, the carrier 126, the seat section 138 along with the rest of the transfer top 124, and the siderails 118 all move horizontally toward a foot end 152 of the support rails 102. The docking station 100, therefore, includes a driver 154 shown in FIG. 3 that moves the carrier 126 along the support rails 102 toward the foot end 152 of the support rails 102 during articulation of the transfer top 124 to the chair position. Movement of the carrier 126 toward the foot end 152 of the support rails 102 facilitates patient egress from the transfer top 124.

It is well known in the hospital bed art that drive motors with various types of transmission elements including lead screw drives and various types of mechanical linkages may be used to cause relative movement of portions of hospital beds, stretchers, chairs and other types of patient transport and support apparatuses (sometimes collectively referred to herein as “patient support apparatuses”). As a result, terms such as “drive mechanism,” “drive assembly,” “drive,” and “driver” are intended to cover all types of electrical, mechanical, electromechanical, hydraulic and pneumatic drive systems that are operable to move portions of a patient support apparatus relative to other portions of the patient support apparatus. In addition, terms such as “articulation mechanism,” “linkage assembly,” “linkage,” and “transmission assembly” are intended to cover all types of components such as belts, gears, racks, pinions, interconnected links, torque converters, ball screws, chains, sprockets, pulleys, cables, and the like, as well as combinations of these, that couple to drive mechanism and that are configured to transfer motion from the drive mechanism to a portion of a patient support apparatus. Reference may be made to U.S. Pat. No. 6,006,379, which is hereby incorporated by reference herein, and which is entitled “Articulating Bed Frame,” for examples of illustrative drive and articulation mechanisms.

The docking station 100 includes a motor package 156 (in phantom) situated behind the room wall 104. The motor package 156 includes a driver that couples to the support rails 102 via a linkage assembly. The driver of the motor package 156 is operable to move the support rails 102 vertically between a raised position, shown in FIGS. 1-3, and a lowered position, shown in FIG. 4. The siderail-mounted controls 148 command the operation of the driver of the motor package 156. When the support rails 102 are in the lowered position, the transfer top 124 is supported at a position close to the floor 112 allowing the patient to egress from a side of the transfer top 124 more easily than when the support rails 102 are at the raised position. The siderail 118 includes a head-end section 158 and a foot-end section 160 that pivots laterally outwardly about a vertical axis in the direction of arrow 162 relative to the head-end section 158 to facilitate patient egress from the transfer top 124 as shown in FIG. 4. Optionally, the siderails 118 may be equipped with interlock mechanisms that operate to lock sections 158, 160 of the siderail 118 together until the support rails 102 are moved to the lowered position.

Referring now to FIG. 5, a first alternative docking station 200 includes a lift mechanism 202 coupled to a wall 204 of a hospital room 206 and a pair of spaced-apart lift arms 208 extending horizontally in a cantilevered fashion away from the lift mechanism 202. The lift mechanism 202 includes drive mechanisms 210 that are operable to raise and lower the lift arms 208 as indicated in FIG. 5 by a vertical double-headed arrow 212. A transfer top 214 includes a mattress 216 and a mattress support deck 218 beneath the mattress 216. The mattress support deck 218 includes one or more receptacles (obscured view) that are adapted to receive the lift arms 208 to couple the transfer top 214 to the docking station 200. The transfer top 214 raises and lowers with the lift arms 208. The docking station 200 includes a suitable controller 220, such as a wall-mounted, pendant or wireless controller, that receives user inputs to command the operation of the lift mechanism 202 to control the elevation of the lift arms 208 and the transfer top 214.

The transfer top 214 includes a leg assembly 222 having one or more coupling members 224 that are received in corresponding receptacles formed in a foot-end portion 226 of the mattress support deck 218, and having one or more retractable legs 228 that are pivotably coupled to the distal ends of the respective coupling members 224 for pivoting movement about a horizontal axis 229 that extends in a transverse direction relative to the transfer top 214 as shown in FIG. 5. The retractable legs 228 pivot relative to the mattress support deck 218 between a use position extending vertically downwardly from the mattress support deck 218 so that wheels 230 coupled to the distal ends of the respective legs 228 engage a floor 232 of the hospital room 206 and a storage position extending horizontally adjacent an undersurface 234 of the mattress support deck 218.

The transfer top 214 is detachable from the lift arms 208 and is attachable to a transport trolley 236. Suitable locking mechanisms (obscured view) are provided for coupling the transfer top 214 to the lift arms 208 and to the transport trolley 236. When the trolley 236 moves in the direction of a horizontal arrow 238 from a first position spaced apart from the transfer top 214 into a second position located beneath the transfer top 214, the transport trolley 236 engages the retractable legs 228 and automatically pivots the legs 228 from their respective use positions to their respective storage positions. After the transfer trolley 236 is in the second position, the transfer top 214 is decoupled from the lift arms 208 of the docking station 200 and is coupled to the transport trolley 236 for transport away from the docking station 200.

According to the present disclosure, a second alternative docking station 300 includes a lift mechanism 302 and a pair of spaced-apart lift arms 304 extending horizontally in a cantilevered fashion away from the lift mechanism 302 through associated slots 306 formed in a wall 308 of a hospital room 310 as shown in FIG. 6. The lift mechanism 302 is positioned to lie behind the hospital room wall 308. In addition, the lift mechanism 302 includes drive mechanisms 312 that operate to raise and lower the lift arms 304. The docking station 300 includes a pair of siderails 314 having controls 316 that are used to operate the lift mechanism 302.

The docking station 300 includes a bolster assembly 320 (also referred to as a bolster) coupled to the pair of lift arms 304 as shown in FIGS. 6-8. The bolster assembly 320 includes a head end portion 322 extending horizontally between the lift arms 304 adjacent to the room wall 308. The bolster assembly 320 also includes a pair of side portions 324 extending horizontally away from the head end portion 322 in parallel relation with the lift arms 304. Thus, the bolster assembly 320 is formed to include a mattress-receiving space 326 between the pair of side portions 324. In some embodiments, the head end and side portions 322, 324 of the bolster assembly 320 include patient support elements, such as one or more air bladders or one or more foam pads, and an outer cover that encases the patient support elements. Each of the siderails 314 is coupled to a respective side portion 324 of the bolster assembly 320 for pivoting movement about a longitudinal-extending axis between a raised position and a lowered position.

A mobile platform 330 includes a transfer top 332 and a wheeled frame 334 that carries the transfer top 332 as shown best in FIGS. 6-8. The transfer top 332 includes a mattress 336 and a mattress support deck 338 beneath the mattress 336. The mobile platform 330 is configured to dock to the docking station 300. However, unlike the docking stations 100, 200 in which the stretcher base 122 and the transport trolley 236 are moved away from the docking stations 100, 200, respectively, after the associated transfer tops 124, 214 are attached to the support rails 102 and the lift arms 208, respectively, the wheeled frame 334 of the mobile platform 330 remains underneath the transfer top 332 when the mobile platform 330 is docked to the docking station 300.

When the mobile platform 330 is docked to the docking station 300, the mattress 336 is received in the mattress-receiving space 326 having upper surfaces of the head end and side portions 322, 324 of the bolster assembly 320 substantially in coplanar relation with the upper surface of the mattress 336. Thus, the bolster assembly 320 cooperates with the mattress 336 to increase the amount of surface area available to support the patient when the mobile platform 330 is docked to the docking station 300. The wheeled frame 334 includes drive mechanisms 340 that are operable to change the elevation of the mattress 336 relative to the floor 342 of the hospital room 310. When the mobile platform 330 is docked to the docking station 300, the operation of the drive mechanisms 312 of the lift mechanism 302 of the docking station 300 is coordinated with the operation of the drive mechanisms 340 of the wheeled frame 334 of the mobile platform 330 so that the mattress 336 and the bolster assembly 320 raise and lower together.

According to the present disclosure, a floor-mounted patient care module 400 includes a pedestal 402 and a pair of lift arms 404 extending horizontally from the pedestal 402 as shown in FIG. 9. The patient care module 400 includes a base panel 406 (also referred to as a base) extending from a bottom portion 408 of the pedestal 402 beneath the lift arms 404 as shown in FIGS. 9 and 11. A transfer top 410 includes a mattress 412 and an articulating mattress support deck 414 that supports the mattress 412. The transfer top 410 is selectively couplable to the lift arms 404 of the patient care module 400 and to a transport base 420.

The transport base 420 includes a lower frame 422 having a cylindrical central hub 424 and six spokes 426 radiating substantially horizontally outwardly from the central hub 424 as shown in FIG. 9. The transport base 420 includes casters 428 coupled to the distal or outer ends of the spokes 426.

Illustratively, the patient care module 702 and the transfer top 704 are of the type shown in FIGS. 9-11. The transfer top 704 and the patient care module 702 are rotatable in the hospital room 700 about a vertical axis 706 between a plurality of positions, including a first position (in solid) having a head end 710 of the transfer top 704 facing toward a headwall 712 in which medical data monitors 714 and various gas supply components 716 are housed, a second position (in phantom) having a foot end 718 of the transfer top 704 facing toward a visitor area 720 of the hospital room 700, and a third position (in phantom) having the foot end 718 of the transfer top 704 facing toward a bathroom area 722 of the hospital room 700. As the patient care module 702 and the transfer top 704 are moved between positions, patient data lines 724 maintain their orientations relative to the patient lying on the transfer top 704 and relative to the patient care module 702. Thus, because the transfer top 704 and the patient care module 702 rotate together about the vertical axis 706, unwanted pulling, entanglement, and disconnection of patient data lines 724 is avoided.

A ceiling support track 730 extends between the transfer top 704 and a toilet 728 included in the bathroom area 722. A patient support device 732, such as a harness, a handle bar, or a seat, hangs from the ceiling support track 730. The patient support device 732 is used by the patient to ambulate to the bathroom area 722 after the transfer top 704 is first moved to the third position having the foot end 718 facing toward the bathroom area 722 and then moved to a chair position allowing patient egress from the transfer top 704. A sink 734 is located in bathroom area 722 in close proximity to the toilet 728. Therefore, the patient has access both to the toilet 728 and the sink 734 while still being supported by the patient support device 732 hanging from the ceiling support track 730. A secondary track 731 extends from the ceiling support track 730 to a shower portion 733 of the bathroom area 722. In some embodiments, an overhead track supported by a framework assembly is used as an alternative to the ceiling support track.
